Pagemethod doesnt work from asmx file rather aspx any suggesion?

Question

I am using simple json method for calling webmethod but it works with aspx file ie url:

'myclass.aspx/myfunction'

but it doesnt work if I put same function in an asmx file and change url to asmx.

Is there anything else have to be done to enable asmx service ?

asmx with vb code: // this works

<%@ WebService Language="VB" Class="WebService" %>

Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols

' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
<System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
Public Class WebService
    Inherits System.Web.Services.WebService

    <System.Web.Services.WebMethod()> _
    <System.Web.Script.Services.ScriptMethod()> _
    Public Function abc(ByVal args As String) As String
               Return returnValue
    End Function

End Class

asmx with codebehind file

<%@ WebService Language="VB"  CodeBehind="default.vb" Class="default" %> //this doesnt work

code behind file

Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols

' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
<System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Public Class mintnow_default
    Inherits System.Web.Services.WebService

    <System.Web.Services.WebMethod()> _
    <System.Web.Script.Services.ScriptMethod()> _
    Public Function abc(ByVal args As String) As String
               Return returnValue
    End Function

End Class

You need to decorate your service with the <ScriptService> attribute if you want to be able to invoke it with a JSON request:

' you need to add the ScriptService attribute here
<System.Web.Script.Services.ScriptService>
<System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
Public Class WebService1
    Inherits System.Web.Services.WebService

    <WebMethod()> _
    Public Function MyFunction() As String
       Return "Hello World"
    End Function

End Class

i added that line _ – Ironsun Jan 25 '12 at 22:33
@user1167053, how exactly does your method signature look like and how exactly are you calling it from javascript? – Darin Dimitrov Jan 25 '12 at 22:35
is it ok if i put code in same file or it matters for security concern? – Ironsun Jan 25 '12 at 22:41
Is this a web site project (File->New Web Site)? That would explain the problem. – John Saunders Jan 25 '12 at 22:47
Web sites are a pain when it comes to anything interesting like web services. Don't use them if you can avoid them. – John Saunders Jan 25 '12 at 23:09
i think you are right for now i will go with single file if i find the exact cause i will put here thanks bydway :) – Ironsun Jan 25 '12 at 23:23

You will have to remove the Shared keyword from the service methods.

hmm what exavtly static keyword?? i dont get you – Ironsun Jan 25 '12 at 22:26
auto generated asmx says to uncomment _ this line i did but its nt working – Ironsun Jan 25 '12 at 22:27
Your Page Methods are, for instance, `public static int SomeMethod(int param)`. Get rid of `static`. – John Saunders Jan 25 '12 at 22:27
its not statis its public shared function – Ironsun Jan 25 '12 at 22:28
So you're using VB.NET. Get rid of `Shared`. – John Saunders Jan 25 '12 at 22:29
i tried that ,still not working it works perfect within aspx codebehind file – Ironsun Jan 25 '12 at 22:31
Can you show a small amount of the code that's "not working"? Also, can you say what you mean by "not working"? – John Saunders Jan 25 '12 at 22:46
code is same as darin mentioned above just in VB there is no error when i say not working means if i put webmethod function in aspx code file or in asmx file json method passes parameter values and webmethod returns right answer but if i put same function in codebhind file same code no change just add a link in asmx file at top codebehind="this.vb" then function doesnt return value on html page it keeps showing loader.gif thats timeout function for executing webmethod – Ironsun Jan 25 '12 at 22:54
The class name is "mintnow_default", not "default". – John Saunders Jan 25 '12 at 23:09
thats typo... actula class is mintnwo_default – Ironsun Jan 25 '12 at 23:10
What is the definition of `returnValue`? I don't see it getting set. – John Saunders Jan 25 '12 at 23:13
hmm it can be anything even return "hello word" is not returning – Ironsun Jan 25 '12 at 23:21
